Unable to attach to \VIM_SQLEXP V-79-57344-33932

I have a sql express instance on my vCenter server that symantec will not backup. It comes up with Unable to attach to \VIM_SQLEXP.

My first few troubleshooting steps have lead me to this point. When I go to backup properties, and I select test/edit credentials, all the accounts work except for SQL instance \VIM_SQLEXP. Error says test failed. The logon account symantec BUE is instructed has dbo rights on the SQL express server. As a test i have even used my domain admin account that also has dbo rights on the SQL server. None of the accounts work and the job continues to fail.

Any thoughts?
